The boats not to bad wasn't very well bit when it was bought so upgraded a few parts works loads better now. Bit of a ball ache getting it set up dragging it down the pond then the fuel and pouring the fuel back because I've not used it all but is really fun to smash it around the pond if you go flat out and turn hard I would say it would be easy enough to flip, touch wood not done that yet :)
I started with a couple of battery ones I like them because you can just go with them without messing about too much.
